Method for establishing plant community in East China

A plant community and construction method technology, applied in the field of plant community construction in East China, can solve the problems of ignoring the scientific design and post-regulation processing of plant communities, not fully considering the maintenance and management costs of environmental conditions, and not combining species with different functions. To achieve the effect of regulating its own physiological functions, promoting the safe establishment of vegetation, and controlling growth potential

Problems solved by technology

From the content of the above patents, it can be seen that there are the following shortcomings: first, the technology focuses on the selection and implementation of engineering measures, as well as the preparation of matrix materials, while ignoring the scientific design of plant communities and post-regulation processing; The basic living habits and ecological characteristics are used to screen species, but species of different types and functions are not reasonably combined; third, when treating seeds, different treatment measures are not taken for different types of seeds; fourth, they do not fully consider Environmental conditions, plant characteristics, and maintenance and management costs, the specific species selected are not highly adaptable; fifth, in the later stage of vegetation establishment, there is a lack of technical means such as growth and competition regulation, and improvement of stress resistance

Abstract

The invention provides a method for establishing a plant community in East China, comprising the following steps of: selecting appropriate seeds of herbaceous plants, shrubs and arbors; processing the germinated seeds; preparing the mixed seeds; preparing the base material mixture; preparing the base material mixture of the seeds; jetting the base material mixture of the seeds; controlling heightof the herbaceous plants and densities of the shrubs and arbors; spraying cycocel soup to the herbaceous plants; spraying stress resistant high nutritive foliar fertilizers to the shrubs and arbors; and finally performing routine management. The method can promote the seeds to germinate rapidly and safely, ensure that the artificial vegetations are structurally and functionally stable, effectively shorten the succession period from the artificial vegetations to the natural vegetations and establish the plant community on wound surface of rock-soil and degraded land of side slopes, waste disposal areas and mining areas and the like in North China.

Description

technical field [0001] The invention relates to a method for establishing artificial vegetation, in particular to a method for establishing plant communities in East China. Background technique [0002] East China includes Shanghai City, eastern Jiangsu Province, eastern Zhejiang Province, Fujian Province, and Anhui Province in Jiangxi except the part of East China, with a total area of ​​220098km 2 . East China has a developed economy, dense population, high degree of urbanization, and high environmental requirements. However, East China is rich in resources, involving many types of minerals and a large number, and the development of mineral resources is common, resulting in a large number of rocky slopes and mining abandoned bare land. Revegetation of regional artificial wounds is a coordinated and sustainable economy and environment in East China. urgent need for development. However, the existing vegetation restoration technology mainly selects suitable plant seeds fi...
